Definitions

  • a heat pump utilizing an indoor coil and an outdoor coil wherein there is provided a hot gas defrost system utilizing superheated gas from the system compressor outlet which is conducted directly into the heat exchanger to be defrosted.
  • the microprocessor loads its memory with a specific code and after a relay switching noise causes a reset, the control detects the specific code and continues its present operation without resetting and restarting at the beginning.
  • frost or ice may form on the outdoor coil 2.
  • the amount of frost and rate of accumulation are dependent upon the ambient environmental conditions.
  • the heat transfer efficiency of the refrigeration system decreases and, therefore, the accumulation of ice must be removed to maintain efficiency within the system.
  • the ice is melted from the coil by circulating hot refrigerant through the coil. While detection of this predetermined amount of ice accumulation to determine an initiation point for the defrost cycle does not form a part of the present invention, such defrost cycle may be initiated periodically by means of a timer, or other suitable system for the detection of an amount of ice on the coil.
  • this control method is especially useful when the control switches a relay causing a possible reset transient. After the relay switching noise causes a reset, the control detects a code and jumps back to its place without a disruption in its operation. No disruption in the operation is accomplished, since the electronic switching of the microprocessor operates many times faster than the time required for the actual movement of the contacts of the relay.
